Video! Lady Gaga Safely Brings Down House on 'Kimmel'

After a riot broke out in Hollywood on Wednesday for the Electric Daisy Carnival premiere, LAPD was prepared in case things got out of control at Gaga's appearance.

But the concert went on without incident. Lady Gaga wrote a note thanking police for keeping her safe, according to TMZ.com.

To thank her fans, Gaga performed six songs instead of the scheduled three. Watch below!

During her interview with Kimmel, Gaga admitted to stealing her style. She donned a hat that spelled out GAGA in feathers. When Kimmel asked how she came up with the idea for it, she said, "This is a Philip Treacy hat. He made one for Isabella Blow many years ago, so you know, I just stole the idea."
